I don't know whether anyone else has done this (forgive me if this is a commonly known thing) but I have coded all the FMC areas into Custom Data, so you can see the boundaries.

Those areas are already in SkyDemon, and you should see them in your Pilot Log before flight, and in the Radio tab during flight. If you tap on them in the radio tab the boundaries will briefly appear on the map.

They are indeed, but it’s a fiddle and temporary, and there is no prompt to do it. It was, though, a useful way to check my work!

The actual motivation for doing this was a meeting with a CAA Infringement Challenge Group, where we were talking about encouraging and reminding people to use listening squawks. The idea is to put them on the map, so people can see them and think “oh, yes, that would be a good idea“!

But, if people are happy with the way SkyDemon does it, perfect!
